-"Welcome To The Hellmouth" - When Buffy is looking for Willow in the Bronze, she snaps
off a stool leg to use as a weapon. In the next shot, it has magically become a regular stake.
- "Phases" - Willow is running away from Oz and trips in the woods, muddying
her overalls. Yet when she enters the library, those overalls miraculously got
clean again.
- "Angel" - When Angel and Buffy are running from the Three, and take refuge
in Buffy's house, one of the Three gets his arm through the door before Buffy
forces him back out. But he was uninvited, so how did he get his arm in? In
other episodes uninvited vamps have hit an invisible barrier across the door
of homes.
- "I Robot, You Jane" - Buffy's birthday keeps changing. According to the
school computer, her birthday is October 24, 1980. In the very next shot, her
birthday is May 6, 1975, and on her gravestones in Nightmares and The Gift,
her birthday is in 1981. Then why does Joss always do the Buffy birthday
episode in January?

projecting the image of a beetle onto the screen behind him.
-"Never Kill A Boy on the First Date" - In the scene where Buffy tells Giles,

is it when she leaves Ethan's store she uses the door? You also hear her walk away.

pushing the Citroen.
